Gold level here, too. I haven't used the clean and check service yet, but I agree with Dave, the kit they send is nice. I converted my CPS strap to a sling style. It works well.
My only beef with them is they send the kit Fedex with a "must have" signature delivery. The Fedex driver can't take a signed door tag. You have to be there to sign. When I renewed my membership, I couldn't be here to sign for the kit because I had just started my new job. The Fedex facility is 31 miles away, so I couldn't go pick it up either. They were supposed to resend it with lesser signature requirements, but they never did. I'll need to chase them down on that now.
